In case of Tsunami, 15.50% of total area of city of Vancouver will be in danger. The danger area is outlined by the criteria of 1km within the shoreline and less than 15m in elevation above sea level. This data is calculated by obtaining the ratio of danger area in Vancouver and the total area of Vancouver in ArcMap. First open attribute table for the data layer with Vancouver land use. Right click shape_area, followed by statistics, then find sum. This will give the total summed area of Vancouver land use, which is 131020600.022 square meter. Within the data frame, there should be another data layer that contains dangered area of Vancouver. This layer is made by intersecting the Vancouver landuse layer and the identitfied danger layer(1km from shoreline, <15m elevtion) created in Arcmap. Within the layer, open attribute table, right click shape_area, followed by statistics, then find sum. The area of danger in Vancouver is 20314805.890824 square meter. Therefore, the percentage of total danger area in Vancouver in case of tsunami is 20314805.890824m^2/131020600.022m^2*100=15.50%.
